Description

Technical Field

[0001] The utility model relates to a die-cutting roller knife process bottom film waste remover, belonging to the die-cutting roller knife process bottom film processing technical field. Background Art

[0002] Mold design and manufacturing technology is the core technology of modern die-cutting production. With the rapid development of modern manufacturing industry, related LCD TVs, smart phones, tablet computers, laptops, smart wearables and other consumer electronic products with display screens and the automotive industry are pursuing efficient, safe and reliable production. At the same time, the quality requirements of spare parts are also increasing, especially the quality and appearance requirements of core parts are getting higher and higher. The covers in 3C electronic products and the automotive industry have the characteristics of thin materials, complex shapes, multiple structural levels, large sizes, high surface quality requirements, and convenient operation and use. Some functional die-cut parts need to be laminated and rolled out of the finished products multiple times during production and manufacturing. For this reason, a large amount of bottom film is required to carry auxiliary lamination. Since the bottom film needs to be discharged and pulled away after roller cutting, the small hole waste generated by roller cutting will be taken away with the bottom film. After the bottom film is rolled up, it is not easy to recycle because of the small hole waste remaining on its surface. It can only be treated as waste. Therefore, how to control and reduce the cost of production auxiliary materials and recycle the auxiliary materials and bottom film has become a technical problem to be solved by technicians in this field.

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-5As shown, the present embodiment is a die-cutting roller knife process bottom film waste remover, comprising a waste stripping system and a negative pressure collection system; wherein the waste stripping system comprises a receiving roller 1, a first guide roller group 10, a scraper group, a second guide roller group 20 and a receiving roller 2, the scraper group is located below between the first guide roller group 10 and the second guide roller group 20, the bottom film 4 carrying small hole waste 3 passes through the receiving roller 1, the first guide roller group 10, the scraper group, and the second guide roller group 20 in sequence, the bottom film 4 between the first guide roller group 10, the scraper group, and the second guide roller group 20 has a V-shaped material travel route, the scraper group is used to strip the small hole waste 3 carried by the bottom film 4, the stripped bottom film 4 is finally wound on the receiving roller 2, the stripped small hole waste 3 falls downward, and the negative pressure collection system is used to collect the small hole waste 3 falling downward.

[0031] In this embodiment, static eliminators 5 are respectively arranged above both sides of the scraper group. Specifically, ion wind copper rod static eliminators can be used to remove static electricity carried by the base film 4 to prevent excessive static load from causing excessive resistance value on the base film 4 after waste removal, affecting the anti-static resistance value of the product material during subsequent recycling, and further affecting product stacking to cause sticky sheets that are difficult to separate.

[0032] In this embodiment, a first auxiliary roller 6 is arranged between the first guide roller group 10 and the scraper group, and a second auxiliary roller 7 is arranged between the second guide roller group 20 and the scraper group. The back side of the bottom film 4 is in rolling contact with the first auxiliary roller 6 and the second auxiliary roller 7, so that the bottom film 4 can move more stably. The first guide roller group 10 includes two first guide rollers 11 arranged horizontally at intervals, and the second guide roller group 20 includes two second guide rollers 21 arranged horizontally at intervals.

[0033] In this embodiment, the scraper group includes a triangular vertical blade 8 and a triangular shovel blade 9. The triangular shovel blade 9 is located on the left side of the triangular vertical blade 8. The angle between the triangular shovel blade 9 and the triangular vertical blade 8 is less than 45°. There is a gap between the edge of the triangular shovel blade 9 and the edge of the triangular vertical blade 8. The bottom film 4 passes through the gap, and the back of the bottom film 4 is in sliding contact with the edge of the triangular vertical blade 8. In order to adapt to the bottom film 4 and the small hole waste material 3 of different thicknesses, the gap is usually set to 1-1.2mm; in this embodiment, the gap is 1mm, and in actual application, the gap can also be 1.1mm or 1.2mm; in order to better peel and remove the small hole waste material 3, the angle between the triangular shovel blade 9 and the triangular vertical blade 8 is usually set to 15°-30°. In this embodiment, the angle between the triangular shovel blade 9 and the triangular vertical blade 8 is 15°. In actual application, the angle between the triangular shovel blade 9 and the triangular vertical blade 8 can also be 20°, 25° or 30°.

[0034] In this embodiment, the triangular vertical knife 8 and the triangular shovel blade 9 have the same structure, both of which include a triangular prism, and cylindrical rods are respectively arranged at both ends of the triangular prism. A U-shaped groove 42 for fixing the triangular prism is arranged on the external side plate 41. After the cylindrical rod at the end of the triangular prism is placed inside the U-shaped groove 42, a nut is threadedly connected to the cylindrical rod for fixing; before the nut is locked, the triangular prism can be rotated to achieve the angle adjustment of the triangular vertical knife 8 and the triangular shovel blade 9; of course, in actual application, other existing angle adjustment devices can also be used.

[0035] In this embodiment, the negative pressure collection system includes a collection tank 31, a pipe 32, a collection box 33 and a vacuum suction pump 34 which are connected in sequence. The scraper group is located inside the collection tank 31. A filter 35 is provided at the connection between the collection box 33 and the vacuum suction pump 34. The filter 35 is used to intercept the small-pore waste 3. After the vacuum suction pump 34 is started, negative pressure is generated in the collection tank 31, the pipe 32 and the collection box 33. Under the action of the negative pressure, the small-pore waste 3 that has been peeled off is not easy to fly around, and the small-pore waste 3 will enter the collection box 33 through the collection tank 31 and the pipe 32, thereby realizing the collection of the small-pore waste 3.

[0036] When the present embodiment is working, the supporting film 4 carrying the small-pore waste 3 passes through the receiving roller 1, the first guide roller group 10, the scraper group, and the second guide roller group 20 in sequence. When the supporting film 4 carrying the small-pore waste 3 passes through the scraper group, the back of the supporting film 4 slides in contact with the edge of the triangular vertical knife 8, so that the small-pore waste 3 carried on the front of the supporting film 4 is lifted up, and with the cooperation of the triangular scraper 9, the small-pore waste 3 is completely separated from the supporting film 4; the peeled supporting film 4 is finally wound on the receiving roller 2, and the peeled small-pore waste 3 falls downward and is collected by the negative pressure collection system. The vacuum suction pump 34 is started to generate negative pressure in the collecting tank 31, the pipeline 32 and the collecting box 33. Under the action of the negative pressure, the small-pore waste 3 enters the collecting box 33 through the collecting tank 31 and the pipeline 32.

[0037] The utility model can peel off and remove the small hole waste remaining on the surface of the supporting film when the supporting film is rolled up, so that the supporting film can be recycled and reused, effectively reducing the input of production auxiliary materials and reducing product manufacturing costs.
